“…Subsequent papers have demonstrated that the rankings of quantities, prices, profits, and welfare are sensitive to assumptions on the number of firms and symmetry of cost and demand parameters (e.g., Häckner, 2000;Zanchettin, 2006). More recently, a number of papers have turned to mixed duopoly where a public, welfare-maximizing firm competes against a private, profit-maximizing firm (e.g., Ghosh and Mitra, 2010;Scrimitore, 2011Scrimitore, , 2013Choi, 2012aChoi, , 2012bMatsumura and Ogawa, 2012;Andree, 2013;Chirco et al, 2013;Nakamura, 2013;Ohori, 2013). Taken together, the papers of Matsumura and Ogawa (2012) and Ghosh and Mitra (2010) provide a (partial) characterization of the effect on the market variables and profits.…”
